[132]. A bellows diaphragm was fabricated with a
poly(ethylene glycol)-based sacrificial molding tech-
nique followed by coating with parylene-C. A pair of
interdigitated electrodes was integrated into the bel-
lows to form an electrochemical actuator that is suit-
able for low-power pumping of fluids.
By optimizing the geometrical factors, a maximum
pump efficiency of 90% ...
